TRACK RAIL.

Application filed November 24, 1925. Serial No. 71,157.

To all whom it may concern:

Be it known that I, HENRY B. UNRUH, a citizen of the United States,residing at Great Bend, in the county of Barton and State of Kansas,have invented certain new and useful Improvements in Track Rails, ofwhich the following is a specification.

This invention relates to track rails for railroads, more particularlyto the ends of a track rail section whereby the ends of adjacent trackrail sections may be interlocked to form a substantially unbrokencontinu ous track rail, and more particularly to an improvement upon theconstruction of track rail sections as set forth in Letters Patentgranted to me April 14, 1908, No. 884,690, and not only possessing theobjects and advantages as defined in the aforesaid'Letters Patent, butfurther has for its object to provide, in a manner as hereinafter setforth, the sections of a track rail with means to prevent theinterlocking ends of said sections from vertical and longitudinal playthereof, at the same time permitting expansion and contraction due toclimatic conditions, and further to provide means for strengthening thejoint between the interlocking ends of the rail sections.

Further objects of the invention are to provide, in a mannerashereinafter setforth, a railroad track rail, which is comparativelysimple in its construction and arrangement, strong, durable, thoroughlyefiicient in its use, readily set up, and comparatively inexpensive tomanufacture.

WVith theforegoing and other objects in,

view, the invention consists of the novel construction, combination andarran ement of parts, as hereinafter more speci cally described andillustrated in the accom anving drawings, wherein is shown an em 0 mentof the invention, but itis to be understood that changes, variations andmodifications can be resorted to which come within the'scope of-theclaims hereunto appended. In the drawings wherein like referencecharacters denote corresponding parts throughout the several views Fi re1 is a fragmentary view, in perspect ve, of one end of a track railsection, in accordancewith this invention. v

Figure 2 is a like view-of the other end of the track rail section.

Figure 3 is a fragmentary view, in plan, pair of track rail sectionshaving the oppos ng ends thereofinterlocked,

Figure 4 is a section on line 44, Figure 3.

A track rail section, in accordance with this invention, comprises abase 1, a'web 2 and a head 3.

Thetrack rail section at one end is provided with an extension, referredto generally by the reference character 4, and at its other. end with anextension referred to generally by the reference character 5. The 65extension 4: is oppositely disposed with respect to the extension 5.Each of said extensions is formed with a complete continua tion of thehead 3, as indicated at 6, and also with a half continuation of the head3 as 7 indicated at 7, and one half of the continuation 6 merges into.the continuation 7. That portion of the continuation 6, which is freeof the continuation 7, has its free end inclining inwardly in adirection towards the inner face of the continuation 7, as at 8.

Each of said extensions is formed with a complete continuation of theweb 2, as indicated at 9, and also with a half continuation of the web2, as indicated at 10, and onehalf of the continuation 9 merges into thecontinuation 10. That portion of the continuation 9 which is free of thecontinuation ,10 has its free end inclined at its inner face to form acontinuation of the inclined face 8. Formed integral with thecontinuation 10 is a continuation 12, which has its inner face ofi'setwithrespect to the inner face of the continuation 10 and is of lessheight than the combined heights of the continuations '3 as and 10. Asthe continuation 12 is offset with respect to the continuation 10 ashoulder 13 is provided at the bottom of the extension and as suchcontinuation 12 does not, extend to the continuation 7 a seat 14 isprovided;

The inner face of the continuation 10 of the extension 4 is formed witha lengthwise extending dovetail groove 15 which starts at the freevertical edge of the eontinuation 10 and terminates at a point removedfrom the point of mergence of the continuation 10 with the continuation9. The groove 15 is closed at its inner end. Formed integral with theinner face of the continua- W5 tion 10 of the extension 5 is a dove-tailtongue 16 which extends from the point of mergence of said continuationwith the continuation 9 and terminates at a point removed from the freevertical edge of the 1 said continuation 10.

When the extension 50f eabk rail see IT at the base of its respectiveextension and which merges into one side of the base 1 of the track railsection; The free end of the other side of the base of the track railsection has its transverse edge formed with a pocket 18 to receive aprotuberance 19 formed on the free end edgeof the flange 17 of anextension.

The inner faces of the continuations 7 and 10 are arranged at thelongitudinal median of the track rail section. The inner face of thecontinuation 12 is positioned at one side of the longitudinal median ofthe track rail section. The vertical free edge of the continuations 7and 10 are inclined, as indicated at 20, and the vertical free edge ofthe continuation 12 is inclined as indicated at 21. The

' continuations 9, l0 and 12 are provided with transversely extendingbolt openings 22;

When the section 4 of one track rail section is mounted in interlockedengagement with respect to the section 5 of an adjacent track railsection, the bottom 23 at the con tinuation 9 seats on the shoulder 13and said continuation 9 is reinforced by the continuation 12, therebystrengthening the joint when the extensions are connected together.

The inclined edge 8, in connection with the inner faces of thecontinuations 7 and 10, provides a pocket. That portion of the in clinededge 20 which opposes the inner face of the continuation 12, forms inconnection with said inner face a pocket. The pocket formed by theinclined edge 8, in connection with the inner faces of the continuations7 and 10, extends through the head and web,

and the pocket formed by the edge 20 extends froin the top of thecontinuation 12 to the shoulder 13. The inclined edges 8 and 20 providetwo pointed projections or noses adapted to interengage in the pocketsas aforesaid. pocket 18.

The adjacent ends of the two railsections are joined by relativelongitudinal movement of the two with the parts held in proper register,and when joined the projcctions of one extension seat in the pocketsformed in the other extension and with the tongue 16 of one extensionseated in the groove 15 of the other extension.

To bind the parts securely together transversely extending bolts 94 areprovided which are passed through the openings formed in the extensions,as the openings in one extension register with the openings in anopposed extension. The, bolts 24 are provided with lock nuts.

The projection 19 engages in the To further hold the extensionstogether, a rail chair 26'ofchannel shape is provided.

It is thought the many advantages of a track rail section constructed inaccordance with this invention, can be readily understood, and althoughthe preferred construc tion of the track rail section is as illustratedand described, yet it is to he understood that changes in the details ofconstruction can he had which will fall within the scope of theinvention as claimed.

\Vhat I claim is 1. A track rail section formed-of a head, web and baseand provided with an extension at each end, said extensions oppositelydisposed with respect to each other, each of said extensions comprisinga half continuation of said base, a complete continuation of said headand web, a half continuation of said head and web extended from thecomplete continuations of said head and web, and a reinforcementintegral with the half base and half web continuations and offset withrespect to such half continuation to provide a shoulder and a. seat.
